Arq/Harq-Related Procedure for Grant-Free Random Access

3. The UE of claim 2, wherein the GF retransmission resource pool is larger than the GF transmission resource pool.

5. The UE of claim 2, wherein the UE is configured to select the GF retransmission resource randomly from the GF retransmission resource pool.

6. The UE of claim 2, wherein the GF retransmission resource pool comprises a plurality of retransmission resource pools, the plurality of retransmission resource pools being of the same size or of different sizes, and the plurality of retransmission resource pools comprising a first GF retransmission resource pool and second GF retransmission resource pool.

8. The UE of claim 6, wherein the GF retransmission resource pool comprises, in addition to the first and second GF retransmission resource pools, at least one further GF retransmission resource pool.

10. The UE of claim 9, wherein the GF transmission coding scheme comprises a first NOMA sequence, and the GF retransmission coding scheme comprises a second NOMA sequence, the second NOMA sequence being more robust than the first NOMA sequence.

12. The UE of claim 11, wherein first UEs use a first further grant-free access occasion that is earlier than the second grant-free access occasion, and second UEs use a second further grant-free access occasion that is later or earlier than the second grant-free access occasion.
